CHARLES NALENCE, or ORANFORD, NEW JERSEY.

' WATER-HEATER AND STEAM GENERATOR.

SPECIFIGATICN-forming part of Letters Patent No. 700,546, dated ma 20, 1902. Application filed January 3, 1902. Serial No. 88,314. (No model.)

To aZZw/"wm it may. concern:

Be it known that I, CHARLES NALENCE, a citizen of the United States, residing at Oranford, in the county of Union and State of New Jersey, have invented new and; useful Improvements in-Water-Heaters and Steam- Generators, of which the following is a speci-' fication.

In steam-boilers, as known, it is desirable to obtain as large a water-heating surface as possible, and the more intense the heat the more violently is the water agitated. At the same time, however, it is desirable to economize fuel as much as possible, and mechanical means for agitating thewater more or less, as required,'will aid the fuel in causing circulation and thorough heating. A small amount of fuel can thus be made to yield or produce the required quantity or pressure of steam.

Myinvention residesin an axle with waterimpelling devices of suitableform, as hereinafter described, said axle or shaft being placed inside a boiler and rotated to secure the'violent moving or stirring of the water required for thorough heating. Said invention is set forth in the following specification and claims and illustrated in the annexed drawings,-:in which V Figure 1 shows a boiler with my improvementin one position, the boiler being of the socalled horizontal type, although the invention is notconfined to such structure. Fig. 2 is a section along x 00, Fig. 1. Fig. 3 shows ahorizontal boiler with horizontal shaft..- Fig. 4 is a section along 'y y,-Fig. 3. Fig. 5 shows a boiler with one large flame-tube of suitable form and stirrer-shafts in vertical position.

' Fig. 6 is a section along .2 2, Fig. 5.

In the drawings the letter A indicates a boiler of any suitable type. Afasteningqail (shown at B, Fig. 1) is adapted to form a bearing for one or more axles or shafts D, which are suitably driven. The shaft D is shown with a water-impelling device E, such as spiral wings or propellers or other suitable form of agitator or mixer. These shafts are suitably supported in pillow-blocks F and receive'motion from gears H on the main or' driving shaft 0. The shaft 0 receives mo- 'by Letters Patent, is

tion from any suitable source, as electricity, steam, orghand-power. shown gears'M, driven by gearIG, whose axle receives motion from apulley L'gsaid-axle-being extended' through a suitablestuffingebox In the'drawings are in an extension or chambe'rL of the boiler,

so that waste or escape of steam is-avoided.

The flame-tubes K need not be specially described.

Modifications can of coursebe made without departing from the invention.

The horizontal shaft D, (shown in Fig. 3,) resting against the end pillow-blocks F, will also impel or stir the boiler-Water; buta series of stirrers, as shownin Figs. land 5, is quick-actin g and efficient. The water atany one point if heated andimpelled by the d riving device to be replaced by another quantity of water less or differently heated will impart from itsheat as it moves :along, and colder particles of water coming to the'points of the boiler directly heated or fired will in turn be rapidly diffused through'or imparted to the entire mass or body of water.

What I claim as new, and desire to secure 1. A boiler provided with a fastening-rail, a driving or main axle, axles driven by the main axle and having a bearing in the fastening-rail, and water-impelling devices carried by the driven axles.

2. A boiler provided with a fastening-rail 1 and pillow blocks,' a driving or main. axle extended longitudinally through the .boiler, axles placed transversely to'and driven by the main axle and'supported in said fastening-rail and pillowblocks, water impelling devices onsaid transverse axles, and driv- 'ing, gears and shaft for the rnain axle, said boiler having a stuffing-boxchamber for the passage of said last-named shaft.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. I I
